The unit circle can be used to calculate the trigonometric functions sin(θ), cos(θ), tan(θ), sec(θ), csc(θ), and cot(θ). It utilizes (x,y) coordinates to label the points on the circle, where x represents cos(θ) of a given angle, y represents sin(θ), and represents tan(θ). Theta, or θ, represents the angle in degrees or radians. This handout will describe unit circle concepts, define degrees … File Size: 442KB Page Count: 6
